Accuracy of cytological exam for diagnosis of inflammatory and proliferative process in domestic animals

The purpose of this study was to demonstrate the importance and accuracy of cytology as a diagnostic method for proliferative and inflammatory processes in domestic animals. The cytology samples were collected by biopsy or during necropsy, using fine needle aspiration or imprint techniques in 80 dogs, 4 cats 3 goats, 2 cows and 1 horse. Histopathology of formalin fixed tissues processed by the routine embedding paraffin technique was used as a confirmatory diagnostic test. Cytology results agreed with histopathological findings in 75 (83.3%) cases. They held higher accord in round cell tumor cases. Therefore, this study shows that cytology is a valuable diagnostic method for diagnosis of proliferative process in domestic animals, especially for round cells tumors.
